Homogeneous aptasensors that eliminate the need for probe labeling or immobilization hold significant potential rapid detection of tumor biomarkers. Herein, a homogeneous aptasensor with electrochemical (EC) and electrochemiluminescence (ECL) dual channels was developed by integrating nanochannel-based enrichment DNase I cleavage selective biomarker, carbohydrate antigen 125 (CA125). A two-dimensional (2D) composite prepared assembling CA125-specific aptamer cationic tris(2,2′-bipyridyl)Ru(II) (Ru(bpy)32+), which exhibited both EC ECL properties, onto graphene oxide (GO) nanosheets (Ru(bpy)32+/Apt@GO). vertically ordered mesoporous silica film (VMSF) ultrasmall, uniform, aligned nanochannel arrays rapidly grown on inexpensive disposable indium tin (ITO) electrode, forming interface. Due to size exclusion effect ultrasmall nanochannels in VMSF, Ru(bpy)32+/Apt@GO unable penetrate nanochannels, resulting no detectable Ru(bpy)32+ signal electrode. Upon specific recognition CA125 aptamer, an aptamer-CA125 complex formed subsequently detached from GO. then cleaved complex, releasing allowing dissociate into solution. This enzymatic enabled re-enter binding cycle, amplifying release The electrostatic adsorption VMSF significantly enhanced signals. constructed linear range 0.1 U/mL 100 ng/mL, limit (LOD) 91 mU/mL. For detection, detected over 0.001 U/mL, LOD as low 0.4 demonstrated excellent selectivity successfully applied dual-mode EC/ECL fetal bovine serum samples.
